Wow, thanks guys! So much good info!
I don't have a ton of money, which makes the K-7 that much more appealing. And I don't take photos for money, just for me.
I don't shoot, or plan to shoot tons of sports, I'd just like the option to. Well, "action", like mountain biking anyway. I don't think that's quite as difficult as "real" sports, where the action is more random.
Another thing I'd like to get into more is "stobist" stuff. I know both the K-7 and d300s can trigger off-camera flashes with the built-in flash, but I'd probably get a hot-shoe remote setup anyway just to not have to worry about line-of-sight issues. (And they're cheap on ebay).
pb_red - I know exactly what you mean about buying into a system. I think if it were "just a camera" I wouldn't be so up in the air about it. When looking at the fast zooms, it's Pentax's SDM vs. Nikon's prices.
Groucho - Yeah, Rowe is where I went. They have Nikon and Canon only.
Arpe - nice rugby photos! What lens are you using for those?
Well, you guys are pushing me towards the K-7. It's not decided yet though.
Certainly much to think about...
